There are a number of ways you can price a job in Streamtime:
Value price - Set a $ figure for the entire job and optionally choose your team when the job starts.
Price by item - Let Streamtime calculate the $ figure for each item based on an items sell rate and total hours you want to use for that item.
Price by team - Let Streamtime calculate the $ figure for each item based on your team members' individual sell rates.
Just set one overall budget for the job - Don't even plan the job - just set a total $ figure in the budget and then let your team pick the job as they work on it from their TO DO lists and hence record time spent on the job as you go.
